Why fight at close quarters when the work can be done standing far away from danger? This is the thinking that has apparently gone into the making of the Gun/knife. Designed by Global Research and Development (G.R.A.D.), this weapon combines two of the most preferred items in any arsenal. Tucked neatly in a formidable looking knife is a .22 caliber 5 shot gun, the trigger of which is located conveniently at the back of the handle. Coming in at $699 this could be just the surprise that you need for an enemy. Hint that you’ll take him on with a knife and then go away shooting merrily. And when you are done, just check the corpse by stabbing once or twice. Gory? Ouch! Hit more for a video.
